Delete files in database dynamically

hi,
what is the code to be used if i want to delete records in the database after a specified time automatically?
eg. lets say i want to clear a table in my database in 24 hours time. this should be done using the codes and not manually
thanks.

hi
have u tried using servlets for this problem of ur's
if it's a web project u could use servlets or else go for threads on a particular thread u may write the code for dynamically deleting the database files and may make this thread sleep for the duration that u might have in mind
myself being a novice at java programming can't come up with a better solution, see to it if this could solve ur problem else we will think of something else.
anyway what exactly are u trying to do with this

How to get Deleted File details from Content DataBase?

Hi,
I have uploaded one pdf document in to SharePoint Document Library. After some days i have removed it.
File has removed from Site.
Does record available in Content Data Base for the deleted file? Which table should i refer?
Thanks & Regards
Poomani Sankaran

Hi,
According to your description, my understanding is that you want to get the deleted file record in sql database table.
If you have backed up the Content Data Base, then you can find the deleted file information in AllDocs andAllDocStreams table. You need to use "inner join" to get the whole information.

Hi,
First of all you must Open a ticket with oracle Support and explore the options
You can use this note to fix it:

How to delete previously deleted files off iphone PERMANENTLY from database

Someone I happen to know hacked my iPhone 4s. They took my iPhone when I left it out. They plugged it into their Macbook and used software I beleive called Wondershare Data Recovery, to raid my phone and go through confidential files I had previously deleted on my phone. They went through text messages, photos and files that were personally confidential to myself. They made it aware they did this because they personal told me they would continue "tracking" what I do on my phone because my files will be backed up onto their computer. I was also made aware that after I decided to put a password on my phone, the person told me "It doesnt matter if you put a password on the phone since my phone is now ENCRYPTED with the laptop".
My first question is how do I go about this situation. Is there a program i can use to fully erase all the "deleted" files i thought were deleted previously on my phone? Is there a data base i can PERMANENTLY delete my files from so they can never be acessed in a data base in the future?
How do I make sure i dont continue to get stalked by this "close friend" in the future?

If you have permanently deleted iPhone file thoroughly, No one can get you personal information and data from iPhone,after you sell, donate or give it away.
To permanently delete photo,video and other files on iPhone,you can use a iPhone data eraser,there are some iPhone data eraser software in the market, but few can be completely and permanently delete the data on iPhone, even if data has been cleared, some professional iPhone data recovery software can recover them later.
Please read this use guide about how to Permanently Erase iPhone Data Before Selling your iPhone.So

Delete file Application Server

Hi ...
I have an application wrote with Forms Dev. ... Is it possible delete a file on the application server ??
Is it also possible delete a file in the Application server by a stored procedure ??
Thank's in advance

It is also possible to implement a java procedure on the database being invoked with a PL/SQL wrapper class.
In this way (and if used right) there is also granularity regarding the filestructure permissions given and it may be called during a Forms or other PL/SQL session.
As it is a requirement in this post to delete file from the AS, the database instance holding the JAVA class needs to be installed on the Application Server itself (which is not recommended anyway). But the article below explains a more generic approach how to invoke shell commands from within an Oracle Instance.
Be careful with this, because it really works ;)

How to create/delete files from filesystem using PL/SQL ? UTL_FILE?

Greetings,
I will start by explaining what i intend to do.
I have an application made in APEX. This application will have among other purposes the managment of pdf files which will reside in the filesystem.
I have questioned the person in charge to keep the pdf files in the database and not in the filesystem but without success.
So the pdf files reside in the filesystem and there is a record in a database table about them. A table keeps all info about the pdf, their location , size and name, creation date etc.
The APEX application will have a mecanism to allow the deletion of the pdf files if an administrator decides.
So it should be possible for an administrator to schedule the deletion of all pdf files whoe creation date is older than 2008 for example
So, how can i achieve that?
After some research i foudn about the UTL_FILE package which seems to have it takes to perform the task in issue.
My idea was to have a script in the operating system which runs nightly and reads a file containing all file names of the pdf to be erased.
The file which contains the names of the pdfs to be erased will be generated by the database a few minutes before.
If there are no pds files to be erased than the file containing the names will simply be empty
Are there any other viable solutions out there?
And as for opening/creating the file withn the pdf names, i use:
UTL_FILE.FOPEN (
location IN VARCHAR2,
filename IN VARCHAR2,
open_mode IN VARCHAR2,
max_linesize IN BINARY_INTEGER)
RETURN file_type;
And as for writing lines (a pdf name per line ), i use;
UTL_FILE.PUT_LINE (
file IN FILE_TYPE,
buffer IN VARCHAR2,
autoflush IN BOOLEAN DEFAULT FALSE);
is there a better solution?
thanks all.

Greetings,
I have read that link above, some questions still though.
I will provide some more information.
-First the database is in a windows server.
The windows server has a virtual drive mounted as z:\ <-- this points to a directory in virtual machine, i can manually access/create/delete files manually,i tested.
-Second utl_file_dir is defined as * , in t that enough to cover mounted drives? ( i can't change the init.ora and reboot the db right now :( gotta wait.. )
Do i explicitly have to define utfl_file_dir = z: ?
-Third haven't had the chance to test it on linux or any other operating system, assuming a virtual unit is mounted successfully and that the issues above are solved i should be able to operate on any mounted drive whatever the os, right?

Uploading data from excel file to a dynamically created internal table

Hi,
I have a requirement where i have to upload data from an excel file into a database table. I would be able to determine the structure of the table only at runtime based on the user input.. so i have created an internal table dynamically.
Could you please tell me if its possible to upload data from an excel file to the dynamically created internal table using any function modules?
I thought of doing this by declaring a generic internal table of one field and then uploading the *.csv file into it and then splitting it based on "," and then assigning it to the field symbol referencing the internal table.. but my file length exceeds 132 characters and i'm only able to get data of lenght 132 char's in my internal table ( generic one).
Could anyone please show me a way around this.

How to load huge size file in database

Hi,
I have a requirement to load files into database and download them as well. Can you tell me which is the best method to do on plsql.
Thanks
Sudhir

The file upload will be a tad ugly.
You need to create an upload form/page in Apex that allows the user to upload the file. The Apache location configuration for that Database Access Descriptor (DAD) will include a parameter called PlsqlDocumentTablename - and this parameter specifies the name of the Oracle (or Apex) table to use for uploads.
The default document table is WWV_FLOW_FILE_OBJECTS$.
The 150Mb file will thus be a LOB in a row in the document table.
You can add a post PL/SQL process to that Apex upload page to process the uploaded document. Because of the size of the uploaded file, I suggest that you start a batch process (via the DBMS_JOB or DBMS_SCHEDULER interfaces) to process the upload file.
Okay, now for the processing. This is the ugly part - as the file is a LOB column in the database and you want to use it via SQL*Loader as an external file or external table. You can write your own CSV parser in PL/SQL. But I do not recommend using this approach for large files - SQL*Loader and external tables are a lot more flexible. I have not yet seen a means to define an external table on a CLOB - so this means having to write code using UTL_FILE and unload the 150Mb LOB contents to an actual external file. Once that is done, you can then use an external table on the external file to load it.
As for sending files to the client via Apex. This is done using the WPG_DOCLOAD.download_file() call to stream the LOB to the client browser. E.g. basic example:
--// URL example: http://my-server.my-domain.com/MyDAD/MySchemaName.StreamFile?fileID=1234
create or replace procedure StreamFile( fileID number ) AUTHID DEFINER is
        mimeType        varchar2(48);
        fileName        varchar2(400);
        lobContent      BLOB;
begin
        --// read the LOB from a table (or dynamically create it)
        select
                f.filename,
                f.mime_type,
                f.blob_content
                        into
                fileName,
                mimeType,
                lobContent
        from    FLOWS_FILES.WWV_FLOW_FILE_OBJECTS$ f
        where   f.id = fileID;
        --// format a basic HTTP header that describes the file stream send
        OWA_UTIL.mime_header( mimeType, FALSE );        -- e.g. text/csv text/plain text/html image/gif
        HTP.p( 'Content-Disposition: attachment; filename='||fileName );
        HTP.p( 'Content-Length: ' || DBMS_LOB.GetLength(lobContent) );
        OWA_UTIL.http_header_close;
        --// now write the BLOB as a mime stream using the Web Procedural Gateway's
        --// doc load API
        WPG_DOCLOAD.download_file( lobContent );
exception when OTHERS then
        --// Decide what HTML to generate (if at all) if there is a failure
        HTP.prn( 'StreamFile() failed with '||SQLERRM(SQLCODE) );
end;

Using an Excel file as a dynamic data source? Opinions needed...

I have posted this topic before, but as always; in order to get the relevant correct answer you have to ask the correct question.
I'm trying to create a number of Pricelists linked to an Excel/CSV file. I have a Excel file that contains Pricelist information which is Product specific.
I have had a number of suggestion that follow:
A direct link to the Excel file. PROs: Excel file can be uploaded on FTP and overwritten if (and when) amended. Linking this is easy peasy in Dreamweaver. Person browsing can download info straight away on request - no hassle. CONs: Simply, not everyone has Excel and those who don't can not access the information.
Import Excel file as tabular data. PROs: Fairly easy to do in Dreamweaver. Person browsing can see info straight away. CONs: Can be time consuming on larger Excel files. NOT amendable (so a number of price changes becomes a big job). Can't simply overwrite Excel file on FTP. Larger Excel files can take a lot of page space and thus require tonnes of scrolling).
Use the Excel file as a dynamic data source. --Not entirely sure how I would go about doing this (any suggestions/links/tutorials etc)-- PROs: ? CONs: Contributor added this suggestion is not a good idea as it performs poorly on the web.
Create a dynamic page using a database and import the Excel file to that....or maintain the price list in the database rather than an Excel file. --Again not entirely sure how I would go about doing this (any suggestions/links/tutorials etc)-- My understanding of this option is that it will require XML data and SPRY work. Is this correct? Can this be someone who is not an advanced user?
If once again, I'm off the mark and better suggestions can be thought - please do so.
As you can see I'm at a bit of a crossroads so an suggestions, comment, help, links, tutorials or applause would be greatly received.
Thanks in advance and looking forward to seeing the comments this throws up!

Hi
Although not everyone has excel just about everyone can open csv files in some way, if not offer the option to download "open office" which is free for the pc, as for the mac they have a program installed by default to use csv files.
The import tabular data is not really an option for the reasons stated.
Use excel as data source - not a good idea, requires asp.net to work correctly otherwise it does run slow and is not recommended if you are expecting more than a very small number of users.
As for the dynamic with database, this can be done with xml and spry but if you have a large amount of data this is almost as bad as the option above. You are probably better creating a database and importing your excel spreadsheet into this, for tutorials on creating a php/mysql database and set-up of testing server see - http://www.adobe.com/devnet/dreamweaver/application_development.html.
No matter which way you go with the last option it will require a fair amount of knowledge and experience to do correctly, efficiently and securely.

Deleting files which are offline.

What is the best way to get Lightroom to delete files which are offline? I don't use lightroom as a database or DAM - for that i use iMatch. I use lightroom only to process the raws and hate to see the thumb files with a question mark on them when they are really not available locally.
Sometimes i wish lightroom behaves like the photoshop bridge program in that it will display only files that are available but i understand that lightroom does what it does because it also acts as a DAM program - that's why it still keeps the thumb files even though they don't really exist locally. But i don't want to see them if they are not available - is this possible and what's the best way to batch delete all question-marked files? Thank-you.

Of course doing as John suggests mean all edits, history, snapshots, collection information, virtual copies are gone, gone, gone.
As you've said yourself, Lightroom is a database, not an browser and having access to offline files is a reason why people use Lightroom. Missing file handling could be better, but if you want to files on a missing volume, click on the Volume browser to close the folder view. Of course you'll still see the missing files in collection.

IPhoto 08 and Deleting Files

I recently upgraded from iLife 06 to ILife 08 and having major problems with new version of *IPhoto 08.* First and foremost, messages began showing that my startup disk is almost full and to delete unwanted files. I'm assuming this is happening because of ILife 08 installation including SuperDuper and Lacie external hard drive. No matter, before doing any installations I did massive backups to external hard drive and cds. Once ILife 08 was installed, I began deleting unwanted pictures within *_IPhoto Library via the Finder_* including File browser when I had Photoshop open. Unbeknownst to me, this is not recommended due to possible corruption of IPhoto. OK, apparent this is happening because when I go to IPhoto there are blank photos when I do a full screen.
My question is what is the best way to delete ALL originals and duplicates of older iphoto 06 pictures including other unwanted pictures in current IPhoto 08 Library? Will I have to uninstall IPhoto 08 then go into my finder and start deleting pictures like I used to do whenever I wanted to delete files? Of course, even then I always had blank photos within IPhoto.
BTW, with ILife 08 installed, I have deleted (trashed) all sorts of applications such as iMovie, and iDVD to free up space. This has made barely any difference. My main criteria is to delete HUGE pictures no longer needed in my IPhoto 06 (or rather IPhoto 08 too) Library Folders. Also considering I'm tapped with my current disk space, currently unable to download any programs such as duplicate annihilator, etc.
Hope this isn't to confusing. Any help overwhelmingly appreciated!
Cheers,
June

Welcome to the Apple Discussions.
Let's get this out of the way:
Don't change anything in the iPhoto Library Folder via the Finder or any other application. iPhoto depends on the structure as well as the contents of this folder. Moving things, renaming things or otherwise making changes will prevent iPhoto from working and could even cause you to damage or lose your photos.
The way to delete pics from iPhoto is to do it in the iPhoto Window. Drag the pics from the Library to the iPhoto trash. iPhoto Menu -> Empty the trash.
Deleting a pic here or there is not going to make a difference to your HD space? How big are these pics? 2 - 5 mb if they're from a point and shoot camera, 10 - 15 from a dslr? Why not move your library to the external disk:
1. Quit iPhoto
2. Copy the iPhoto Library Folder as an entity from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.
As you've been mucking about in the iPhoto Library Folder then you'll need to start over and create and populate a new library:
To create and populate a new library:
Note this will give you a working library with the same Events and pictures as before, however, you will lose your albums, keywords, modified versions, books, calendars etc.
In the iPhoto Preferences -> Events Uncheck the box at 'Imported Items from the Finder'
Move the iPhoto Library to the desktop
Launch iPhoto. It will ask if you wish to create a new Library. Say Yes.
Go into the iPhoto Library (Right Click -> Show Package Contents) on your desktop and find the Originals folder. From the Originals folder drag the individual Event Folders to the iPhoto Window and it will recreate them in the new library.
When you're sure all is well you can delete the iPhoto Library on your desktop.
In the future, in addition to your usual back up routine, you might like to make a copy of the library6.iPhoto file whenever you have made changes to the library as protection against database corruption.
To use Photoshop with iPhoto:
You can set Photoshop (or any image editor) as an external editor in iPhoto. (Preferences -> General -> Edit Photo: Choose from the Drop Down Menu.) This way, when you double click a pic to edit in iPhoto it will open automatically in Photoshop or your Image Editor, and when you save it it's sent back to iPhoto automatically. This is the only way that edits made in another application will be displayed in iPhoto.
